你好，朋友，我正在使用此代码保存主题选项。现在我想显示的主题选项，这是在前端保存，以及如何保存在这个主题选项我卡在它的标志。

<?php
/*
 * Add the admin page
 */
add_action(\'admin_menu\', \'options_admin_page\');
function options_admin_page(){
    add_menu_page(\'options Settings\', \'options\', \'administrator\', \'options-settings\', \'options_admin_page_callback\');
}

/*
 * Register the settings
 */
add_action(\'admin_init\', \'options_register_settings\');
function options_register_settings(){
    //this will save the option in the wp_options table as \'options_settings\'
    //the third parameter is a function that will validate your input values
    register_setting(\'options_settings\', \'options_settings\', \'options_settings_validate\');
}

function options_settings_validate($args){
    //$args will contain the values posted in your settings form, you can validate them as no spaces allowed, no special chars allowed or validate emails etc.
    if(!isset($args[\'options_email\']) || !is_email($args[\'options_email\'])){
        //add a settings error because the email is invalid and make the form field blank, so that the user can enter again
        $args[\'options_email\'] = \'\';
    add_settings_error(\'options_settings\', \'options_invalid_email\', \'Please enter a valid email!\', $type = \'error\');   
    }

    //make sure you return the args
    return $args;
}

//Display the validation errors and update messages
/*
 * Admin notices
 */
add_action(\'admin_notices\', \'options_admin_notices\');
function options_admin_notices(){
   settings_errors();
}

//The markup for your plugin settings page
function options_admin_page_callback(){ ?>
    <div class="wrap">
    <h2>options Settings</h2>
    <form action="options.php" method="post"><?php
        settings_fields( \'options_settings\' );
        do_settings_sections( __FILE__ );

        //get the older values, wont work the first time
        $options = get_option( \'options_settings\' ); ?>
        <table class="form-table">
